Pelvic mass Jonathan Blankenstein and Amy Toderian
Objectives • 4233 List pelvic tumors of ovarian origin. • 4234 Classify ovarian pathology as benign vs malignant. • 4396 Compare and contrast functional vs neoplastic ovarian cysts.
Case • An 18 year old woman presents to your office for routine gynecologic examination.
History • What do you need to ask?
History • GyneHx Review • ID: age, occupation, relationship with partner, gravida, parity • Menstrual Hx: age at menarche, characterize menstrual cycle, LMP, age at menopause, use of HT, dysmenorrhea • Sexual Hx: Age at first intercourse, partners, types of sexual activity, previous STIs, use of precautions (pregnancy and STIs), dyspareunia • Pap smear Hx: date of last pap, abnormal paps and follow up, HPV
History • HPI: She reports that her last menstrual period began about 23 days ago. It was light in flow, and lasted 4 days in length. She has minimal dysmenorrhea. She denies any history of sexually transmitted infections, and has been sexually active with two male partners in the last 2 weeks. She has no children, and has never been pregnant. She was given a prescription for OCP 3 months ago. • ROS: No concerns.
History • MEDS: None – has not filled OCP prescription • ALLERGIES: None • PMX: Healthy with no hospitalizations or surgeries. • Immunizations: Up to date, Gardasil • FHx: Non-contributory • SHx: Lives at home with mom, dad and younger brother. Mom is a teacher and Dad is a government worker. Has a part-time job at Walmart. Attends U of O. Has private health insurance and drug coverage through Dad. Denies being in a relationship.
Physical Exam • OMG, now what?
Physical Exam • GENERAL: Alert and oriented, no visible distress, healthy glow. • VITALS: HR 60 RR 12 BP 110/74 T 36.5 spO2 100% • External exam: Normal female genitalia. • Speculum exam: No visible abnormalities, no blood or discharge • Pelvic exam: 6 cm nontender left adnexal mass that is mobile • Abdo exam: No rebound, guarding or tenderness
DDx Adnexal Mass • Ovarian mass • Physiologic (functional) cyst • Benign ovarian neoplasm • Ovarian cancer or metastatic disease • Extra-ovarian mass • Tubo-ovarian abscess, hydro/pyosalphinx, ectopic pregnancy, appendiceal abscess, diverticular abscess, inflammatory bowel disease, fallopian tube malignancy, fibroids
Physiologic cysts • “Post-menarchal-premenopausal, small, transient”
Physiologic cysts • “Post-menarchal, premenopausal, small, transient”
Benign Ovarian Neoplasms • What’s this?
Benign Ovarian Neoplasms • Teratoma – germ cell tumor with ectodermal predominance, 90% of ovarian tumors in young women, removed surgically when > 8 cm. • Endometrioma – growth of ectopic endometrial tissue, 20% of endometriosis presentations, associated with dysmenorrhea, pelvic pain, dyspareunia, and/or infertility • Serous cystadenoma – Arises from surface epithelium, common in middle adult life, papillary epithelium is contained within a fibrous walled cyst filled with serous fluid, • Mucinous cystadenoma– Arises from surface epithelium, common in middle adult life, multiloculatedwith sticky gelatinous fluid rich in glycoproteins
Ovarian malignancies • NEED TO RULE THIS OUT
Ovarian malignancies • NEED TO RULE THIS OUT • Increased risk of malignancy: • Prepubescent or postmenopausal female • A complex or solid appearing mass (on imaging) • Known genetic predisposition (BRCA) • Presence in a woman known to have a nongynecological cancer (eg, breast or gastric cancer)
Ovarian metastases Sites of origin of the primary: • Breast – 30% • GI Tract – 20% • Endometrium • Lung • Kidney Spreads by direct invasion, surface implantation, lymphatics, blood.
Investigations – Imaging • The next step is ultrasound • Transabdominal, Transvaginal, Doppler • Simple Cyst, Complex Cyst, Solid • (Don’t do an X-Ray) • CT or MRI reserved for special cases
Investigations – Lab • CBC w Diff • Beta hCG • CA 125 • Other tumor markers • AFP, hCG, LDH
RMI = a x b x c a b c >200 = high risk of malignancy
Management • Observation (+f/u) • Suppression • Surgery/Excision • Referral to GyneOnc Not worried Worried
When to Consider Surgery: • Emergency surgical management is indicated in: • Torsion • Ectopic pregnancy • Appendiceal abscess • Ruptured TOA • Hemorrhagic cyst with hemodynamic instability • Not emergency surgery is indicated when: • Simple Cyst (Persistent, Mass Effect, Enlarging) • Complex Cyst (Persistent, Mass Effect, Annoying) • Solid Cyst (especially if obstructing!)
When to Consider GyneOnc: …high risk of underlying malignancy
Case revisited • What if this were our patient?
Management of post-menopausal pelvic mass • Cancer until proven otherwise! Same approach: • History • Physical • U/S • CA 125 • RMI
